Answer:
384 square cm
Step-by-step explanation:
Fabric used will be equal to the total surface of the cubical block.
This expression is easier than it looks like. I thought that to solve it you have for example to express the 2 via 10 * 5^-1 and stuff like that - but you can multiply and divide this expression by some factor. In our case first we multiply by conjunctive expression root(5-2root2) and the second by root(6+2root5). In first we get root16 and the second calculate.
The answer is:
(-28/81)/(-2/3) = -84/(-162) = 42/81
Work
Think of this simple question:
Two number when multiplied together give 15. If one number is 5, then the other is (15/5)=3.
In this form, slope is simply the coefficient in front of <em>x.</em> Therefore, the slope of this graph is -1/4
